This is a starting point for making sense of (and gaining access to) all of the Firefox-related data analysis tools. There are a number of different tools available, all with their own strengths, tailored to a variety of use cases and skill sets.
sql.telemetry.mozilla.org (STMO) site
is an instance of the very fine Re:dash software, allowing
for SQL-based exploratory analysis and visualization / dashboard
construction. Requires (surprise!) familiarity with SQL, and for your data to
be explicitly exposed as an STMO data source. Bugs or feature requests can be
reported in our issue tracker.
(ATMO) site can be used to launch and gain access to virtual machines running
Apache Spark clusters which have been pre-configured with access to the raw data
stored in our long term storage S3 buckets. Spark allows you to use
Python or Scala to perform arbitrary analysis and generate arbitrary
output. Once developed, ATMO can also be used to run recurring Spark jobs
for data transformation, processing, or reporting. Requires Python or Scala
programming skills and knowledge of various data APIs. Learn more by visiting
the documentation or
Offers notebook interface with shared, always-on, autoscaling cluster
(attaching your notebooks to
shared_serverless is the best way to start).
Convenient for quick data investigations. Users can get help on
channel on IRC and are advised to join the
telemetry.mozilla.org (TMO) site is the
'venerable standby' of Firefox telemetry analysis tools. It uses aggregate
telemetry data (as opposed to the collated data sets that are exposed to most
of the other tools) so it provides less latency than most but is unsuitable for
examining at the individual client level. It provides a powerful UI that allows
for sophisticated ad-hoc analysis without the need for any specialized
programming skills, but with so many options the UI can be a bit intimidating
for novice users.
Distribution Viewer (deprecated) was a simple tool
that provides a set of cumulative distribution
for a pre-specified selection of Firefox user metrics. These metrics are
extracted from a 1% sample of the
clientIds from Firefox Telemetry. These plots
will allow you to understand how values of different metrics are spread out
among our population of users rather than just using a one number summary (such
as a mean or median). By viewing the entire distribution, you can get a sense
of the importance of behavior at the extremes as well as anomalies within the
population that might indicate interesting behavior. Very simple to use (no
programming required) and able to provide interesting insights, but not usually
suitable for ad-hoc analysis.
The "real time" or "complex event processing" (CEP) system is part of the ingestion infrastructure that processes all of our Firefox telemetry data. It provides extremely low latency access to the data as it's flowing through our ingestion system on its way to long term storage. As a CEP system, it is unlike the rest of our analysis tools in that it is up to the analyst to specify and maintain state from the data that is flowing; it is non-trivial to revisit older data that has already passed through the system. The CEP is very powerful, allowing for sophisticated monitoring, alerting, reporting, and dashboarding. Developing new analysis plugins requires knowledge of the Lua programming language, relevant APIs, and a custom filter configuration syntax.
